ANDREIV ANDERSON, OFDETROIT, MICHIGAN, ASSIGNOR TO THE IMPROVED MATCHCOMPANY, OF SAME PLACE.

MACHINE FO R SANDING MATCH-BOXES.

SPECIFICATION forming part of Letters Patent No. 570,244, dated October27, 1896. Application filed October 14,1895. Serial No. 565,646. (Nomodel.)

Be it known that I, ANDREW ANDERSON, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Machines for SandingMatch Boxes, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The invention consists in the construction of a machine for sandingmatchboxes, or what is generally known as the match-box shucks.

The invention consists in the construction, arrangement, and combinationof the various parts, all as more fully hereinafter described.

In the drawings, Figure 1 is a sectional perspective of a machineembodying my invention. Fig. 2 is a longitudinal section therethroughbeside the sanding-wheel. Fig. 3 is a detail section illustrating theconstruction of the presser-roll for applying the glue; and Fig. 4 is across-section on line 00 at, Fig. 2.

My machine is usually applied as an attachment to a machine for makingthe tube from which the .shucks are out and which I shall refer tohereinafter as the blank. The various parts may be driven from anydesired source of power.

A is a suitable frame, in one end of which are the feed-rolls 13, bothlive rolls, for feeding the blank 0 flat upon and over the table D. Onthis table are the guides E, having the overhanging lip F, beneath whichthe edges of the blank engage and are guided, these lips serving to holdthe blank flat upon the table. Beneath the table is a glue or paste potG, in which runs the paste-'apply ing roller or wheel H on the shaft I.The upper edge of this wheel projects through the aperture J in thetable and preferably slightly projects above the top of the table, asshown in Fig. 2.

K is a scraper shaped to embrace the upwardly-moving portion of thewheel II and supported on the arm L, which has a straight portionengaging a horizontal guide M below the table and the upwardly-bentportion N extending over the paste-pot. This scraper has the offset 0 atits outer end, through which the set-screw P passes, engaging 111 ascrew-threaded bearing in the frame, and by means of which the scrapermay be accurately adjusted in relation to the paste-wheel.

R is a presser-roll journaled on the end of the lever R, fulcrumed on apin in the lugs R on the table.

S is an adj listing-screw working in a screwthreaded aperture in thetable and passing through an aperture in the end of the lever R. Thescrew S is provided with a head for operating it, which head is adaptedto limit the upward movement of the end of the lever R, through which itpasses. Sleeved on the adjusting-screw between the lever and the tableis a spring S, tending to lift the end of the lever and depress the rollR on the opposite end. It will be seen that by this ar-- rangement ifthe screw be turned down the spring will be compressed and the rolllifted and that if the head of the screw be raised the spring will causethe end of the lever to follow it, and consequently lower thepressure-roll. I am thus enabled to adjust the pressure by which theblank is pressed by the roll R upon the paste-wheel for any thickness ofmaterial.

In line with the paste-roll is a second aperture T in the table, belowwhich is the rapidly-revolving toothed wheel T, secured on a shaft U,journaled in opposite sides of the sand-box V, secured below the table.

V is a hopper spouted t0 the sand-box for supplying sand thereto.

The feed-rolls and the paste-roll H, I have shown as driven byintermeshing gears and the sanding-wheel by an independent drive ,belt VThe blank being brought to the feed-rolls is fedthrough the same uponthe table, its edges being guided as described. The paste is applied asthe blank passes between the rolls II R, the spring S pressing the blank(through the upper roll) upon the pastingwheel. While the paste is wet,the blank is fed over the sanding-wheel, which throws the sand uponit,va thin layer adhering to it and producing a thorough even sanding.The guides prevent the force of the sand or the air from thesanding-wheel from lifting the blank, so that with this construction nosand will get upon the table and such portion as its end, a bearing inwhich said arm is supported and slides, and a set-screw carried by saidoffset and engaging a stationary part of the machine for adj Listingsaid arm, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
